perforations

Completion engineers feel pressure to maximize production per acre and minimize the downsides of fracturing in tight spaces. Terry Palisch, talks about promoting knowledge sharing as part of JPT’s tech director report.

This paper presents the evolution of a Bakken advanced completion design with the added enhancement of extreme limited entry (XLE) perforating. With this strategy, an operator has consistently stimulated more than 11 perforation clusters per stage.

An early commitment to integrate MPD into an HP/HT drilling operation can make MPD more than just an enabling tool and turn it into a performance tool that offers significant operational benefits.

Good reservoir detective work costs money, but two studies show how it can help identify even more expensive problems.

This work is a study of collapse pressure of perforated pipes to evaluate the effect of lateral perforations on the radial resistance of pipes under external pressure.

Significant production gains are being made with hydraulicly fractured wells using diversion to stimulate a higher percentage of the perforations.

An advisor at Schlumberger discusses the company’s work in examining the effect of perforations on hydraulic fracture initiation.

Optimizing laterals by integrating data from many sources to address reservoir variability and structural challenges can increase shale well productivity.

What is observed when an unconventional well is fractured is often at odds with what was expected by those who planned the job.

Achieving greater efficiency in perforation systems can help lower operating costs, particularly when completing long horizontal wellbores in unconventional plays.
